ATTORNEY Patented Jen. 7, 1930 g PArENToFFlcE LON E. WEST, 0F WAYNESBUBG, PENNSYLVANIA ABSOBBEB Application meu August 1s, 1927. serial m. 212,73;

This invention relates to smoking pipes embodying among other characteristics means for absorbing nicotine and other extraneous matter whereby cool dry smoke may be drawn through the pipe stem. Y

Another object of the invention comprehends a chamber carrying a suitable absorbent and which forms the necessary connection between the bowl neck and stem therefor.

A further object of the invention contemlates' means for separating the absorbent groin the pipe stein whereby the passage of smoke therethrough will be unrestricted.

An additional object of the invention consists of means carried upon the pipe stem to elevate the connecting end thereof from the bottom of the chamber to prevent retrograde movement of saliva through the pipe stem.

With the above and other objects in view, the invention further consists of the Jfollowing novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claim.

In the drawings Figure 1 is a longitudinal sectional view taken through the invention.

Figure 2 is a fragmentary longitudinal sectional view, illustrating a bushing connection between the pipe bowl neck and chamber.

Figures 3 and 4 are illustrative of diiierent forms of bushings adapted to establish communication between the pipe bowl neck and chamber.

Figure 5 is an end view of one end of the pipe stem with the modified form of connection bushing.

Figure 6 is an elevation of a separate member. l

Figure 7 is a detail view illustrating the relative arrangement of 4the chamber and separating member.

Referring to the drawing in detail, wherein like characters of reference denote corresponding parts, the reference character 10 indicates a pipe bowl having a neck 11 extended an appreciable distance therefrom.

A sleeve or barrel 12 is telescopically engaged with the free end of the neck. A pipe stem 13 is likewise connected wlth the barrel or sleeve. The barrel or sleeve is iilled with a suitable absorbent, such as indicated at,14 .and banked or compressed against a reticulated wall 15 abutting a shoulder 16 adjacent one end of the sleeve or barrel. A convex foraminated disk 17 is positioned against an annular shoulder 18 integral with sleeve 12 arranged at the opposed end of the shoulder 16 in order that the wall 15 and disk 17 may-be relatively spaced, the purpose of which will be readily apparent.

--Such arrangement will cause smoke drawn through the neck 11 from the pipe bowl 10 to be passed through the absorbent 14 carried by the barrel or sleeve 12. The wall 15 will prevent the absorbent from being drawn through the imperforate portions of the disk 17. The inner end of the pipe stem 13, is 1n addition, provided with a reduced and tapered extension 19 having a flared ferrule 19 disposed in juxtaposition to one side of the disk 17 and axially of the longitudinal center of the barrel or sleeve and above the bottom thereof whereby saliva and other extraneous matter previously induced through the pipe stem will not be subsequently drawn through the pipe stem due to the relative position of the extension and of the ferrule acting as a bafle thereon.

In Figure 2 of the drawing I have illustrated a modiication ofthe invention comprehending-as a. general characteristic the incorporation of a removably connected bushing for the reduced extension ascarried upon the pipe stem in the form of the invention as previously described. The connection is effected by threading a bushing 20 upon the reduced extension upon the pipe stem the bushing providing an annular flange 21 engageable with one end of the sleeve of the barrel 12 and against which the shoulder portion of the stem abuts.

The connection between the sleeve and bowl neck is accomplished through the instru- In Fi ure k3 of the drawingI have illustrated e ongated extensions 24 carried upon a bushing 25 and tapered through its length and adapted for frictional engagement with a correspondingly shaped bore communicating with the bore of the neck 11. The sleeve l2 being connected with the opposed end of the bushing 25 in the manner as provided for the form of the invention as illustrated in Figure 2 of the drawing. In Figure 3 the pipe stem is provided with an extension similar in shape to the extension 24 for the bushing 25 and which is adapted for frictional engagement with the interior of the bushing member 26 having threaded connection with the adjacent end of the sleeve member 12.

In Figure 4 of the drawing friction joints are used throughout.

Figure 5 is an end view of a pipe stem and bushing therefor, the latter being provided with a hexagon shaped flange portion to permit ease when the parts are separated for cleaning. In like manner the adjacent ends of the sleeve and pipe stem may be correspondingly constructed to present a more uniformv appearance both as to design and workmanship.

In Figures 6 and 7 of the drawing Ihave illustrated a convex disk member 17 which is adapted to abut an annular shoulder, at the periphery thereof, within the sleeve 12 and instead of abutting a shoulder 16 in the preferred form of the invention, the disk per se is provided with stud members 29 engage- 'able with the adjacent side of a reticulated wall to space the same from the disk.

The construction described is believed to provide'a long felt want among pipe smokers, due to the fact that the smoke is strained through the absorbent material, cleans the same of nicotine, thesleeve member 12 being preferably constructed of metal and having a natural tendency to cool the smoke, the reticulated wall is adapted to prevent the absorbent from being sucked or drawn within the bore of the pipe stem, the disk member as spaced' from the reticulated Wall is adapted to prevent the absorbent from becoming rendered ineffective by the admission of saliva within the sleeve member 12. The various forms of bushings as carried upon the connecting ends of the pipe stem are adapted to centrally dispose the bore thereof within the sleeve member to prevent the saliva, finding its way within the sleeve member 12, from retrograde movement through the pipe stem. The flanged portion upon the forward extremity of the particular bushings being also adapted to serve as baiiies to overcome such diiiiculty. f A

The invention is susceptible of various changes in its form, proportions and minor details of construction, and the right is here- I inreserved to make such changes as properly fall wlthin the scope of the appended claim.

Havin thus described the invention, what is claime is A smoking pipe comprising a sleeve member having connection at its ends with the adjacent extremities of the pipe bowl neck and stem therefor, an absorbent carried within the sleeve member being spaced from the adjacent end of the pipe stem by a reticulated disk member, a foramin'ated disk member `carried within the sleeve and ydisposed in .spaced relation to the aforementioned disk In testimony whereof I afiix my signature. i
